Key Findings
BIAB, or Builder in a Bottle, has moved from a niche strengthening treatment to what European trade press now calls the most requested service in many salons. Beauty Launchpad's review of Spate data recorded over 1.5 million combined Instagram and TikTok views and posts for BIAB, and industry forecasts point to 15 to 20 percent annual sales growth through 2026. For nail technicians and salon owners, the practical question is not whether BIAB is popular. It is whether it earns a dedicated, correctly priced menu slot rather than sitting as an underpriced gel add-on.
BIAB did not arrive as a color trend or a design fad. It arrived as a technique shift, which is why it behaves differently from most things tracked in nail trend data. Clients are not asking for a look. They are asking for their natural nails to stop breaking.
That distinction matters for how professionals should read the numbers behind it.
What The Data Shows
Beauty Launchpad's coverage of Spate data found that BIAB nails had captured 1,578,756 combined views and posts across Instagram and TikTok, a volume the outlet noted was strong even though BIAB does not rank as highly in raw US search terms as color-led trends. That gap between social attention and search volume is not a data quirk. It is the clearest signal in this report.
One beauty content analyst put it plainly when reviewing UK search behaviour around builder gel: it is a nail trend that is huge with clients, salons, and on TikTok, but is not being reflected proportionally in search data. For a nail tech deciding whether to train, or a salon owner deciding whether to promote it, that means search-volume tools alone will understate real demand. The signal to trust is booking behaviour and in-chair requests, not keyword volume.
European trade coverage has gone further, with one industry publication stating that structured manicures have evolved from a niche strengthening treatment into the most requested service in many European salons, positioned as the bridge between a standard gel polish and heavier hard-gel extensions.
Brand investment supports the same read. The GelBottle, the company credited with originating the BIAB category, continues to expand its shade ranges as a core product line, while OPI has entered the category with its GELevate builder system and Orly has launched GelFX Builder In A Bottle. Three major suppliers competing in the same product category within a short window is a stronger commercial signal than any single trend forecast.
What This Means For You
Why This Trend Is Happening Now
The causation here is client-led rather than aesthetic. Years of acrylic damage, heavy filing, and at-home gel removal mishaps left a large share of clients with compromised natural nails. Structured manicures answer a specific complaint: strength without the weight, chemical intensity, or removal damage of acrylic.
The mechanism is genuinely different from older systems. A structured or BIAB manicure uses a high-viscosity builder gel to create an apex, a reinforcement point on the natural nail that absorbs pressure and resists cracking, rather than simply coating the nail the way standard gel polish does. That structural difference is why nail educators increasingly treat it as its own technique category rather than a gel polish variant.
Clients aren't booking a color. They're booking a repair plan for nails that acrylic and at-home gel already damaged.
Training providers have responded accordingly. BIAB now supports its own accredited certification pathway at multiple nail schools, distinct from general gel polish or acrylic extension training, and some advanced masterclasses require prior gel and e-file certification as a prerequisite. That is not how a passing trend gets treated in an education pipeline. It is how a durable service category gets treated.
What It Means For Professionals
For nail technicians, the training decision is largely settled by the data. BIAB is not a new specialism sitting apart from existing gel skills. It is an extension of gel polish competency, which lowers the barrier to adding it, and industry pricing guidance consistently points to a premium of 20 to 30 percent over standard gel work once offered.
For salon owners, the sharper decision is menu structure, not just pricing. Trade guidance recommends tiering the service explicitly, positioning standard gel as the entry option and BIAB or structured manicure as the reinforced, longer-wear upgrade, rather than listing it as a flat add-on buried under gel polish. The apex structure is a legitimate technical reason for the price gap, and naming it in consultation is what makes clients accept paying more for it rather than assuming it is simply a more expensive polish.
There is also a retention mechanic worth building into scheduling. Because BIAB requires an infill every three to four weeks to maintain the apex, it creates a recurring booking cycle that is more predictable than color-led services, which clients often skip or replace with at-home options between visits.
What This Means For Salon Owners
For brand marketers and product developers, the competitive response from OPI and Orly against The GelBottle's originating position confirms this is now a contested product category rather than a single brand's niche success, which typically signals a multi-year commercial runway rather than a seasonal spike.
Where This Trend Is Heading
BIAB sits closer to Accelerating than Emerging on a trend maturity scale. The technique has already passed the point of being a single brand's product line, has generated its own accredited training pathway, and shows sustained rather than seasonal social engagement. What has not yet happened is full normalization into mainstream search behaviour, which is precisely the gap between the social data and the search data noted earlier in this report.
That gap is worth watching rather than dismissing. Trends that build social and salon-floor demand before search catches up tend to have longer commercial lives than trends that spike in search first, since the latter often reflects one-off curiosity rather than repeat behaviour. BIAB's infill cycle mechanically produces repeat bookings, which is a structural reason to expect continued growth rather than a plateau in the next 12 months.
The open question for 2026 and beyond is whether structured manicures fragment into sub-categories the way gel polish did, with hard BIAB, soft overlay BIAB, and HEMA-free formulations each developing distinct client bases. Suppliers are already moving in that direction with expanded shade and formulation ranges, which historically precedes exactly this kind of segmentation.
The service that grows fastest in search isn't always the one filling your appointment book. BIAB is the clearest current example of that gap.
